摘　　要：从统计的角度对发动机可靠性信息进行统计分析、数据预处理、定制可靠性指标并进行整机可靠性指标的计算,从而得到发动机及其零部件的失效规律。在此基础上建立了一套发动机可靠性数据分析系统。应用结果表明:该系统的实施有助于提高发动机的可靠性水平和故障诊断效率,降低发动机维修成本。The analysis method of reliability data and the computation method of the reliability index were presented based on the analysis of the practical fault sample of diesel engines. The failure law of the diesel engine and its parts was obtained through the relia- bility data analysis and a reliability data analysis system was established. Application shows that the proposed method and the estab- lished system could improve the reliability level and the fault diagnosis efficiency and reduce the maintenance cost for the engine.
